Answer 2

Solving the Problem

To solve this problem, we need to find out how many examples each girl solved out of 40 in 5 minutes. Natasha solved 3/8, Masha solved 2/5, and Anya solved 3/10 of the examples.

Let's calculate the number of examples each girl solved.

Natasha: The number of examples Natasha solved = (3/8) * 40 The number of examples Natasha solved = 15

Masha: The number of examples Masha solved = (2/5) * 40 The number of examples Masha solved = 16

Anya: The number of examples Anya solved = (3/10) * 40 The number of examples Anya solved = 12

So, Natasha solved 15 examples, Masha solved 16 examples, and Anya solved 12 examples.

Therefore, Natasha solved 15 examples, Masha solved 16 examples, and Anya solved 12 examples out of 40 in 5 minutes.
